Does exchange-related volatility make you lose trust in holding your assets on centralized platforms?

An attacker exploited the Ethereum EIP-7702 authorization system on October 29 to compromise a Binance hot wallet. The breach resulted in the unauthorized sale of 7.77 trillion PEPE tokens valued at $31.66 million.

Why it matters

The breach highlights systemic risks within the Ethereum EIP-7702 authorization framework when integrated into high-volume exchange hot wallets. This event prompted significant market volatility, driving liquidations and shifting derivatives volume.

The attacker liquidated 7.77 trillion PEPE tokens at an average price of $0.0000041. Market data shows a 59.84% rise in PEPE futures volume to $1.52 billion, contrasted against a 10.09% decline in open interest to $369.85 million.

The players

Binance

A global cryptocurrency exchange providing a suite of trading services including spot, futures, and hot wallet custody solutions.

Ethereum

A decentralized, open-source blockchain platform that executes smart contracts and hosts the EIP-7702 authorization standard.

The details

The attacker gained unauthorized access to Binance hot wallets by exploiting the EIP-7702 authorization system, an Ethereum improvement proposal designed to allow externally owned accounts to behave like smart contract wallets. By manipulating these authorization parameters, the actor bypassed standard security protocols to move assets. Following the sale, market activity surged as traders reacted to the liquidity event.

Timeline

  1. October 27, 2026: Justin Sun's PEPE holdings were identified.

  2. October 29, 2026: The Binance security breach occurred.

  3. 03:00, October 30, 2026: Liquidations reached $1.53 million.

  4. October 30, 2026: The hacker sold tokens while a whale purchased 45.08 billion PEPE.

The Tech Race

The incident serves as a stress test for Ethereum EIP-7702, which aims to improve account abstraction and user wallet flexibility. It marks a critical security milestone for protocols competing to standardize how hot wallets authorize transactions.

Exchange users may experience temporary withdrawal or deposit latency while hot wallet security protocols are audited following the exploit. Traders utilizing derivatives should monitor market volatility, as futures volume increased 59.84% following the token liquidation.

The takeaway

This breach underscores the volatile nature of new authorization standards in production environments. Investors should monitor future updates regarding the integrity of the EIP-7702 system for signs of further vulnerabilities.
